摘    要:异化Fe(Ⅲ)还原微生物是厌氧环境中广泛存在的一类主要微生物类群,它们的共同特征是可以利用Fe(Ⅲ)作为末端电子受体而获得能量。鉴于土壤Fe(Ⅲ)异化还原是厌氧环境中影响碳、氮、磷及金属元素生物地球化学循环的重要因素,对Fe(Ⅲ)异化还原在环境中的作用进行评述,系统介绍了国内外有关Fe(Ⅲ)还原环境效益的研究现状及其发展趋势。

关 键 词:异化Fe(Ⅲ)还原  环境效益  电子受体

Abstract:Dissimilatory Fe(Ⅲ) reducing microorganisms are dominant groups widely present in variety anaerobic environments, which share the common features with the ability to use Fe(Ⅲ) as the terminal electron aeceptor to gain energy. Fe(Ⅲ) dissimilatory reduction have a major impact on the biogeochemical cycling of carbon, nitrogen, phosphorus and (trace) metals under anaerobic conditions. The effects of soil Fe(Ⅲ) dissimilatory reduction on environment were reviewed in this paper. The status and prospect of the environmental benefits of disimilatory Fe(Ⅲ) reduction were also discussed systemically.
Keywords:environmental benefits  electron acceptor
